Abstract: 767,110. Waterproofed regenerated cellulose yarn; coated fabrics; laminated materials. COURTAULDS, Ltd. Nov. 24, 1954 [Nov. 25, 1953], No. 32682/53. Class 140. Regenerated cellulose yarn is impregnated with an aqueous wax emulsion and then bonded to a polyvinyl chloride composition. Yarns obtained from viscose, cuprammonium cellulose or cellulose acetate may be used. The wax emulsion may contain paraffin wax, a protective colloid such as casein or gelatine, and compounds of aluminium such as aluminium acetate, aluminium formate or alum. Thepolyvinyl chloride composition may be applied to the impregnated yarn as a paste before or after weaving or applied in sheet form to the woven fabric. In an example, viscose yarn in the form of a cake, obtained from the centrifugal spinning process, is impregnated with an aqueous paraffin wax emulsion. It is then impregnated with polyvinyl chloride paste and woven into a belt which is then covered with polyvinyl chloride paste and subjected to heat and pressure. Belts may be made by weaving a number of superposed warps wherein each of the warps is treated with a polyvinyl chloride paste before or during weaving and the belt, when woven, is covered with a preformed sheet or paste of polyvinyl chloride and subjected to heat and pressure. Laminated articles may be made by weaving wax emulsion impregnated yarns into a fabric, spreading both sides of the fabric with polyvinyl chloride paste, heating to gel the paste, folding or assembling several of these coated fabrics, covering the laminated plies with a preformed sheet of a polyvinyl chloride composition and subjecting the composite article to heat and pressure.

Fig. 2 shows in schematic form a non-linear circuit for producing from an input signal applied at 1 an output signal which varies according to the function a, b, c shown in Fig. 1. The potentiometers P1, P2, P3 are set to produce three outputs having the slopes required for the parts a, b, c of the curves shown in Fig. T. The output from potentiometer P2 is supplied to an adding device Al to which is also applied a variable bias source from potentiometer P4 and the output from the adding device is applied to one input of a double diode discriminator tube V5 to the other input of which is applied the output from potentiometer P1. The discriminator V5 passes anode current only from that cathode which has the lower voltage applied to it. The third voltage derived from potentiometer P3 is applied to an adding device A2 to which a bias voltage derived from potentiometer P5 is also applied and the output of adder A2 is applied to one input of the double triode discriminator V6 to the other input of which is applied the output from discriminator V5. The output from the discriminator V6 will follow the more positive of the two inputs applied to it. In the circuit described, Fig. 3, for carrying this into effect, cathode follower isolater stages are provided between the various inputs and resistor networks provide the function of the adding circuits Al, A2 (Fig. 2).
